煤层瓦斯渗流特性研究进展

Advances in study on seepage flow property of coalbed methane

  • 摘要: 针对非线性瓦斯流动理论和煤层瓦斯流固耦合理论存在的问题,以及越来越多高温矿井引发的瓦斯灾害治理难题,在综述煤层瓦斯渗流研究进展的基础上,对国内外学者在非线性瓦斯流动理论、地温场效应的瓦斯流动理论以及煤层-瓦斯流固耦合理论3方面的研究成果给予了重点评述,展望了地球物理场作用下煤层瓦斯渗流特性研究领域的发展趋势。研究显示,在非线性瓦斯渗流、深部开采引起的高温和低渗透问题以及煤层瓦斯的流固耦合问题等方面,还需做更深层次的探索。

     

    Abstract: In the view of probems in non-linear methane seepage flow theory and coalbed methane liquid & solid coupling theory,and difficulties of methane control in the more and more high temperature mines,based on sum-marizing the study evolution of coalbed methane seepage flow at home and abroad,non-linear methane seepage flow theory,earth temperature field effect and methane seepage flow theory,and coalbed methane liquid & solid coupling theory were reviewed especially,and the development trend of research on coalbed methane seepage flow under the effect of geophysical field was indicated.The results showed that deeper study is required in the problem of non-linear methane seepage flow,the problem of high temperature and low permeability methane seepage flow with deep mining and coalbed methane liquid and solid coupling for solving effectively the problem of coal bed methane seepage flow in production.
